RELATED APPLICATIONS

This patent application is a continuation of patent application Ser. No. 11/482,698 that was filed on 07/06/2006, is entitled “LOCATION BASED FORMAT SELECTION FOR INFORMATION SERVICES”, and that is hereby incorporated by reference into this patent application.

BACKGROUND OF THE INVENTION

1. FIELD OF THE INVENTION

The invention relates to telecommunications, and in particular, to location based format selection for telecommunication information services.

2. DESCRIPTION OF THE PRIOR ART

Telecommunication service providers increasingly offer specialized dialing services to customers. For example, some providers offer customers information services related to particular events. A customer can dial a specialized phone number for an event and their provider will connect the customer to a service that provides information related to the event. A typical information service often times includes a media unit that plays out an audio information stream to a customer over a bearer connection. In such a case, the connection between the customer handset and the media unit requires a bandwidth amount similar to any comparative voice call. Information services for sporting events, such as auto races, have become very popular.

One drawback from the perspective of a service provider is that a large number of customers could call a single information service nearly simultaneously and from a single location. In the case of wireless telecommunications, a large volume of calls to an information service could overwhelm the portion of a wireless network serving the location.

In the prior art, one solution to the above problem is to temporarily increase wireless capacity at certain venues or locations around the time of a popular event. In this manner, the bandwidth will exist to service a large number of information service calls from a particular location, in addition to any regular voice calls. Unfortunately, provisioning and deploying temporary service equipment is expensive and inefficient. Regardless, the actual bandwidth demand could still exceed that provided by temporary equipment.

Another solution in the prior art is to block any call that could cause the total bandwidth in-use to exceed the bandwidth capacity of the network. However, blocking a call regardless of whether the call is a voice call or an information service call could result in customer dissatisfaction. In addition, monitoring the available bandwidth of a wireless network on a per-call basis could be overly onerous.

SUMMARY OF THE INVENTION

An embodiment of the invention helps solve the above problems and other problems by providing methods, systems, and software for providing information services in various formats, depending upon the location of a caller. In this manner, the delivery of an information service to a large number of callers within a particular geographical region or location could be optimized, rather than having to block calls or otherwise provide substandard service.

In an embodiment of the invention, a wireless transceiver receives a request message from a caller system for an information service. The information service is associated with an Internet address and an image format. A control system determines a location of the caller system. The control system selects a text message format for the information service based on the location of the caller system. The control system transmits a setup message to the information service indicating the selected text message format. In some embodiments, the control system receives a text message from the information service responsive to the set-up message, and the wireless transceiver transfers the text message to the caller system.

In an operative example, call control system 630 could receive a session request from caller system 610. The session request could indicate the location of caller system 610 in sector 621. In one example, signaling from transceiver system 620 separate from the session request could indicate sector 621.

In response to the session request, call control system 630 could query database system 635 with the identity of the requested information service 650 and the location of caller system 610. In this case, the location is sector 621. Database system 635 could process the query with the translation tables and return a response to call control system 630 identifying a preferred format for the information service 650 with respect to requests originating from sector 621. The preferred format could be one format of multiple formats, such as audio, text, video, and picture formats.

Upon receiving the response from database system 635, call control system 630 could transmit a setup message to information service 650 identifying caller system 610 and the preferred format for the service. In response, information service 650 could provide the service in the preferred format. For example, an audio module in information service 650 could play-out an information stream to the user of caller system 610. In another example, a text messaging module could generate and transmit a single or series of text messages to caller system 610 for display to the user.
